7? Claims. 1

This invention pertains to improvements in filling controlling means for so-called shuttleless looms. The invention is more specifically devoted to improvements in means for presenting the filling to the inserting means and for controlling its release as inserted especially in looms of the type in which filling from a source of supply carried externally of the filling inserting means is presented to that means to be laid in connected pairs of individual picks frequently termed hairpins.

It is a general object of the invention to simplify shuttleless looms of the type herein described and to efiect more efficient handling of the filling as it is presented to the inserting means and to control the filling to a greater extent during its insertion, thereby to. eliminate certain difficulties which have arisen due to the general tendency of the filling yarn to become entangled or otherwise assume unintended condition, which in some instances has. led to filling breakage or other difiiculties requiring. stopping of the loom and repairing or remedying the conditions prior to continuing weaving of relatively perfect fabric.

It is a more specific object of the invention to devise a method and mechanism by which the filling may be presented to the inserting means in the simplest possible manner and with a minimum of mechanical parts involved; also, to provide mechanism and to control it in a manner to make certain that the filling yarn is always maintained under positive control insofar as is reasonably practicable.

Gther objects of the invention will become. apparent from the following more detailed disclosure.

In these so-called shuttleless looms filling from a rather large supply located externally of the inserting means of the loom is presented to carriers reciprocated into and from the shed formed by the warp threads and is controlled, generally speaking, in a manner as described in U. S. Patcnt 1,515,102. According to the method employed, filling thread from a source of supply is controlled in a manner to be contacted by and car ried within the warp shed, being projected toward the center thereof in the form of a doubled length of material whereupon, a transfer of that thread is effected from the carrier inserting it to a secand carrier or instrumentality which draws a severed or relatively free end thereof across the fabric thereby completing the pick. According to the more general scheme employed, these picks are inserted as connected pairs and the operation may be efiected entirely from one side of the loom, or may be performed from both sides, the simpler practice being to insert from one side only, although that has the disadvantage of forming a natural selvage at that side only While the other side of the fabric must be specially treated in order to render it self-sustaining, although several methods of effecting the formation of a selvage at that side are available.

The general mode of operation of such filling controlling means is generally understood by those skilled in the art and specific means therefor is described in our application Serial No. 71,622 now Patent No. 2,604,123; The filling controlling means includes certain clamping or binding devices, a cutter operated with one of the binding means, and filling guiding and depressing means, the latter being employed for deflecting the filling into the pathway of the inserting means, that having been effected in various manners, one satisfactory means for that purpose including mechanism by which the filling is so presented at adjacent picks as to be inserted under the same general conditions as to position, tension etc. That however, requires additional mechanism and it is one purpose of the invention herein described to provide simplified filling controllin means which shall not require periodic reversing of the filling or more complicated mechanism for so controlling it that at each of two adjacent interconnected picks, the t nsion onditions shall. e sim l ly luen e in that the fr e end of the m er al shall al be dispo ed in the same re a ive po i i n with respect to insertin devices The invention as here n ft r desc in 1 tail generally includes a simplified fi lin controlling mean which c mp ses a nder adiacent the supply of filling, a guiding means at that point which may form more or less an integral part of the said binder, a second binder and cutter cooperating therewith adjacent the selvage of the fabric to be woven and between these, a filling depressing and retaining means which functions in a peculiar manner as will hereinafter be described, to deflect the filling out of its more normal pathway into one in which it shall be engaged by the inserting means and which also, at appropriate times serves to retain the filling and to release it at a predetermined instant during the cycle of insertion as has been found to be most satisfactory both with spect to pr pe nsion c nt o a d h remeat to prevent ng unint nded enta gl m o the filling and. s m l r undesi ed oots, a l of which have been experienced at times and which iead to f ulty performance of the loom and the we ng or unsatisfactory material.

Now referrin to Fi s. 1 and 2, as embled views of the filling controlling means or filling motion, the eneral disposal and pur ose of parts will be indicated. These filling motions are carried by and to some extent enclo ed within a casing 20 which is in turn detachably connected by means of screws or other attaching means to an end bracket on the 100m framework. It is to be understood that a filling controlling means is to be found at that end of the loom at which the filling supply is located and from which the filling is inserted and in the event insertion is to be from both sides, then one such assembly is necessary at each end of the loom. The simpler form of the mechanism will be described here and it is to be understood that these parts are to be duplicated at the other end of the loom in the event the loom is of the type acting from each end and forming a selvage at both sides of the fabric.

The filling supported outside of the filling controlling means first enters a periodically actuating binding or clamping means generally indicated by numeral 2! and described here in greater detail in a later paragraph. This clamping means is carried at the end of a bracket 22 attached to the casing and is operated through a reciprocating rod 23 which is in turn caused to function by cam means which are herein indicated by numeral 24 and are adjustably maintained for rotation with a cam shaft 25 supported in end bearings 25 and 2'! which actually form a part of the casing 26 and which are provided with suitable bushings or other bearing members within which the shaft is adapted to rotate freely.

This shaft is rotated one revolution 'for each two picks inserted, that is, in the event filling is controlled from one side of the loom only. Rotation of the shaft is derived from any convenient continuously moving part of the loom,

for example, the cam shaft thereof, and said rotation is imparted through bevel or other gear 28 and 29 which are adapted to impart the proper rotational speed in accordance with the design of other parts which need not be described or shown here.

Before and after passing through the binder 2!, the thread is guided through independent guide means 36 and 3!, these being attached to the binder and serving to maintain the general alignment of the filling in passing therethrough and to prevent it from dropping out of the binding elements or moving away from the control thereof whenever the binder itself is opened.

At the innermost part of the'filling controlling mechanism there is provided what will hereinafter he termed an inner binder or clamp and cutter generally indicated by numeral 32 and which will be described hereinafter by more specific reference to Figs. 6-8. These parts are carried by an arm or bracket 33 detachably connected to the casing 253 and are controlled through a plunger or rod 34 guided in the bracket 33.

This inner binder and cutter are controlled by the cams generally indicated by numeral 35 and which will be described in greater detail hereinafter, it being understood that these cams are likewise adjustable upon the shaft 25, but are normally fixed in an adjustable position thereon as were the cams 24.

The motion derived from cams imparted to the binder 2! through the rod 23 and also through a tappet 3% slideable within the casing as illustrated in these Figs. 1 and 2. and carrying at a forked end adjacent the cam a follower roller 3?. Return movement of the parts is effected through spring 33 which is under compression between the hearing or sustaining lug St on bracket 22 and an adjustable collar ii; fixed in position on rod The rod 23 is also passed through a second bearing lug ii thereby to be maintained in proper alignment. The tappet 35 is prevented from rotating in its sliding guideway by a suitable key or other appropriate means 42. The inner binder and cutter controlled through the plunger or rod 3% likewise re-' ceives its movement from cams 35 through a second tappet 43 and follower 4!!- which are virtually the same as the parts just above described. The rod 34 passes through bearing lugs 15 and 45 and is always urged in a direction to press the tappet follower M against the cams as it is under the influence of compression spring 4! between lug and a collar 48 which is adjustably positionable on the plunger in a manner similar to that employed with respect to the collar 40.

Now referring to Figs. 1, 2 and 9, the filling is controlled as it passes between the binders 2i and 32 by certain mechanism including a depressor 49 which cooperates with a resiliently mounted plunger 50, these elements being caused to move through predetermined pathways during the cycle by the swinging motion of an upper depressor arm 5! and a lower depressor arm 5-2, these being pivoted at 53 and each having. an upwardly directed, extending arm 54 and 55, respectively, by means of which they are swung to and fro under the influence of cams 56 and 51, respectively.

These cams are mounted adjustably on the shaft 25 and as they rotate, their motion is conveyed to the arms 54 and by means of tappets and followers shown dotted in Figs. 1 and 2, but not requiring further description since they are substantially like the tappets Q2 and 43 and their roller followers, except that each of the tappets has an extension by means of which it engages at about the mid-point of the arms 55 and 55 as illustrated in Fig. 2. Springs 51! and 59 are attached at the upper ends of the arms 54 and 55 and also to a fixed spring holding clip 59 expressly provided for the purpose.

As shown more clearly in Fig. 9, the depressor 43 is of angular form so as to pass to the rear of and above the filling inserting carrier SI and tape 62 on which the carrier is fixed and is also pivoted at a pivot point 63 at the relatively free end of the upper arm 5!. The depressor is also provided with a lug 64 by means of which it is also pivoted to the connecting link 35 through a pin or pivot 66, the link 65 also being attached at its opposite end by the pivot pin 6'! at the relatively free end of the lower depressor arm 52. The depressor 49 also has a point or hook 68 which extends from the upper more or less horizontally disposed part thereof when the depressor is in the full line position, Fig. 9, and this hook 658 forms with the said horizontal part of the depressor a notch 69 within which the thread is engaged as will hereinafter be described.

The action imparted to the depressor by the came 55 and 5! is one in which it moves from the dot-and-dash line position of Fig. 9 in which it is relatively inactive and entirely disposed below the pathway of the inserting carrier, to the full line position at which it contacts a resiliently mounted plunger ill to cooperate therewith in retaining the filling until such time as it is desired that the same be released. The cams are adapted to move the depressor to an intermediate position as will be described later with reference to Figs. 16 and 18, wherein the filling is controlled within the notch 65! for the purpose of permitting it to be taken by the carrier, but at which no contact made between the point 558 and the plunger Ill. That provides for presenting the filling to the carrier, but permits the filling to be quickly released in the event such release is desired, for example, during the insertion of the first pick of a connected pair of picks.

Now referring more specifically to Fig. 9, the plunger M is slideable within a suitable bearing for the same as provided by a smooth aperture in cylinder H which is in turn attached to the upper arm 5! by a screw or bolt l2. As shown in Fig. 9,. the plunger 10 is turned down as at 13 to extend through a clearance hole at the lower end of. the cylinder II, it being understood that the aperture for the plunger is continued almost all the way through the cylinder, but not clear through. A spring I4 is enclosed. in an annular space between the plunger and the lower face of the opening in which the plunger moves and is maintained under compression since a nut 55 is threaded onto the correspondingly threaded end of the extension or stem (3. By means of this nut '55, the height to which the plunger may rise may be adjusted. The plunger itself is grooved as at it for the reception of the end of a screw ll passed through the side of the cylinder H and locked in properly adjusted position by the nut 18. This prevents rotation of the plunger so that the nut 15 may be tightened or loosened for efiecting adjustment as is desired.

The angular position of the entire plunger assembly may be adjusted by loosening the clamping screw 12 and by turning the adjusting screw 19 in an appropriate direction to swing the assembly about its pivot as is required. The screw I9 bears against the lower side of a laterally projecting lug 80, Fig. 9a, cast integrally or otherwise suitably formed as a part of the bearing for the plunger, the adjustment of the screw being locked by nut 8| whereupon the entire as sembly may be secured in position by tightening the screw 12. Thus it becomes apparent that the angular disposition of the plunger assembly may be adjusted within reasonable limits, and that also the projection of the plunger above the upper edge of the bearing boss H may be regulated by adjustment of the nut 15, it being understood that the hardened top surface of this plunger is relatively smooth and flat and that it serves as a cooperating contacting member against which the end of the similarly hardened point 58 bears when the depressor has been moved forwardly to its fullest extent, the plunger then receding into its cooperating cylinder as required so that the adjustment is one in which the contact is made and then the plunger depressed slightly thereby to make it unnecessary to provide a particularly fine positioning adjustment for the parts. The point 68 of the depressor is normally curved slightly in the direction in which the filling is to be drawn or slipped therefrom, that facilitating the release of. the filling immediately after the carrier has passed the lateral plane of the depressor, and. after lifting the point fill so that it clears'the top surface of plunger it if that point is not already in raised position. The dot-anddash line position of the plunger is herein given to show approximately the upper setting for the part, while the full line position shows about the amount which it may be desirable to press the plunger downwardly so that the depressor may always trap the thread but permits ready release thereof when. desired.

Now referring to Figs. 3 and 4, the binder plunger 81 passes through the laterally extending lug 39 and is guided therein, being retained Within an aperture formed in the lug and which is just large enough to provide a sliding fit for the plunger. The remainder of the plunger is turned down as at 88 and is passed through a smaller aperture in the end of the boss or part of the casting 89 in which this resiliently pressed binder member is retained to be threaded at its outer end and to have a nut 90' threaded thereon for the purposes of adjustment and. retention.

Spring 9| serves to press the plunger and the abutment portion 86 thereof in a direction to be contacted by the movable binder element 82 as the rod 23 is moved to the left or toward the front of the loom under the influence of spring 38 whenever the cam permits such movement.

The thread would obviously drop out of control or to a position so that it would not return to the binder once released, except for the fact that guide members 30 and 3! are provided. The guide member 30 is attached to one side of the end of the bracket 22 and is notched as illustrated in Fig. 3 so as to hold the thread upwardly within an oppositely directed notch in the cooperating guide 30' formed as a part of the bracket, and to which the guide 30 is attached. The guide 3| is notched as at 52 for permitting the threading or entrance of the thread downwardly into the guiding eyelet Q3 within which it runs once having been threaded. ihis guide 3! is attached to the end of the rod 23 and is clamped in position against the hub 33 by nut 84, the lateral extension 8 serving for attaching purposes. In threading the loom, the filling is first entered between the guides 3i! and 30' and into the notches therein, whereupon it is then entered up between the binder members 82 and 86 and is then passed through slot 92 into the eyelet or opening 93. It may be drawn through the binder if the same is in open position, but will be suitably retained thereby at other times. The timing of these elements will be described in greater detail in later paragraphs. Thumb pieces A are used to open the clamps as when inserting a thread.

Now referring to Figs. 6, '7 and 8, the inner clamp and cooperating cutter 32 are so devised that movement of the rod 34 opens both and then closes both, the timing of the parts being such that the cutting occurs slightly before the thread is clamped. The rod 34 has attached at the outer end thereof a hub 95 clamped in position by nut 96 and having a depending portion 91 which has a laterally disposed, more or less vertical face 98 which acts to clamp or bind the thread against a cooperating binder member 99 at the end of a plunger Hill suitably guided in the boss at extending laterally from the bracket 33. This boss 35 is apertured both for the rod 34 and for this plunger we, the latter extending into a drilled opening in which is provided a spring Nil surrounding the reduced endlflZ of the plunger Hill and adjustably tensioned since the reduced end of the plunger extends through the opening or bearing in which it is guided and has a nut Hi3 threaded at the end acting as a retaining stop member and also as an adjustment for positioning the abutment 89 as desired.

At one of the faces of the depending part 91 is attached one part of a shear or cutter member, this part comprising a blade HM adapted to engage in a shearing relationship with the second blade H35 which is in turn attached by a screw I to the side of the boss 55 and being suitably adjusted for proper shearing cooperation by a screw I01 threaded through an extension 108 of the bracket 33 and being locked in properly adjusted position by means of the nut I09. The binder and cutter are shown in closed position at Figs. 6 and 7, a thread having been cut and retained as illustrated, and in open position in Fig. 8,'the thread being illustrated there as it is about to be cut and then clamped.

The cam 24, Fig. 14, is in fact comprised of two cams adjustably positioned with respect to one 8 another on the shaft 25 and being adjustable in known manner by means which hold their hubs to the shaft. The cam rotates in the direction shown by the arrow and as the inclined part of the cam indicated by numeral H0 engages the follower 31, that, through the tappet and rod 23 serves to open the clamp thereby releasing the filling passing therethrough. The clamp remains open throughout the major portion of the rotation of cam 24 or for something like the time required for about one pick and half the next pick until the follower rides down incline H! of the cam thereby permitting spring 38 to close the clamp. It remains closed then for about onehalf a pick or one-quarter of the time required for a complete cycle of two picks. By adjusting the two cam parts with respect to each other, the proportion of the time which the clamp shall remain closed relative to the time it remains open may be adjusted within limits. The important point in adjustment is the clamping of the filling, and that may be very accurately regulated.

Now referring to Fig. 15, cam 35 is similarly constructed and adjusted, although the extents of the active surfaces and the shape thereof varies considerably from that of the cam 2 The rotation is in the direction of the arrow and the rise 5 92 provides for opening the inner clamp and cutter 32 thereby to release the filling for the first pick. The parts then remain open to the point lit at which time the clamp and cutter start to close, whereupon the follower i i eventually rides down the incline lill thereby to complete the cutting and binding of the filling which remains held in that manner throughout the remainder of the cycle and until the incline H2 is again active to release the filling for the first pick. Likewise, these functional parts of the cam may be adjusted within reasonable limits for the purpose of regulating the time at which the bind ing and cutting and releasing occur, and also thereby to effect proper timing of the parts so that the picks of filling may be of the proper length. Of course, if the loom is to be changed over to weave a difierent width of material, then these cams must be adjusted accordingly.

Cams 5% and El, Figs. l0-l3, control the dcpressor throughout the cycle and cam 55 functions upon the upper depressor arm 5! while the other cam functions upon the lower arm 52. It is the combined and simultaneous movement of these arms which gives to the depressor its pecu" liar movement and the upper parts of these cams as indicated by numerals H5 and iii": function during the weaving of the first pick, while the opposite half of the cams controls the second ick. It is normally better to release the filling from the depressor hook 68 just as soon possible after the carrier has taken the filling, or at a point slightly farther along in the cycle from that illustrated in Fig. 16. The movement of the depressor under the action of the top parts of the cams just above mentioned such, as shown in this Fig. 16, that it extends the filling across the pathway of the carrier, but does not trap it against the plunger iii. If desired, that might be done and the cam modified slightly by providing it with a projection at the proper point which would move the depressor throughout that tional extent or to the extent indicated in Fig. Q. In actual practice the deflected filling is taken in the receiving notch of the carrier and since the hooked end 63 of the depressor is slightly curved in the direction towards the center of the loom,

9 upon further movement of the carrier, the filling slips very quickly from the point.

At the second pick as illustrated in Figs. 18 and 19, the depressor has an initial and a secondary movement imparted thereto, the initial movement being substantially the same as thatfor the first pick, Fig. 16. However, at that particular time the disposal of the filling is slightly differ-- ent, since for the first pick, the filling is held at the inner binder while at the second pick it has been released therefrom and extends from the fell of the fabric back through the guide 3 I outer clamp, etc, to the supply S. For purposes of clarity and to simplify the illustration, the outer clamp is not shown in these schematic figures, and also, the other parts are shown in rather simplified form. The upper depressor arm is controlled by the cam surface H! to move the depressor to the position of Fig. 18 in which deflects the filling so that it may be taken by the carrier. It is desirable at the second pick that the filling be not released from the depressor hook 58 until the carrier has inserted its filling yarn to a substantial extent within the shed and to hold the filling as illustrated in Fig, 1-9, the extension H8 which is in fact made adjustable by an insert H9 which may be moved by the eccentric adjustment I20, the period of time which the said filling may be retained is a variable one. This insert l'9 fits within a slot in the cam 56 as illustrated in Fig. 13 and the eccentric adjustment therefor is adapted to move it circumferentially so that the point 12] at which the filling is released may be varied. After the filling has been permitted to be released from point 68 which has in this instance contacted and pressed against the plunger 1-0, the parts return to their initial position as they did at the first pick.

Cam 51 is similarly constructed and has an extension or added projection I22 and an insert I23 by means of which the depressor is controlled for retaining the filling as above described. It is to be understood that both cams are effective, one upon the arm 51 and the other upon the arm 52, it being the combined motion of these arms that affects the actual movement of the depressor and the eventual extent to which the point 68 is moved as and for the purposes described.

Referring to Figs. 16-19, Fig. 16 shows a point in the cycle just prior to the taking of the filling by the carrier 6!, the depressor having moved to its fullest extent as governed by the parts H and H6 of the cams 55 and 51 whereupon after a slightly greater movement of the carrier to take the filling so that it may not escape from the notch I24 in the carrier, the filling slips from the point 68 and the cycle continues by further insertion of the pick drawing filling from the supply S until the inner clamp 32 is opened thereby releasing the end, that point being controlled by the part H2 of cam 35, Fig. 15, and being dependent upon the amount of material necessary to reach across to the opposite side of the fabric. It is to be understood that the outer binder is also closed at about that time so as to stop further drawing of filling from the supply.

The second pick as illustrated in Fig. 18 is first drawn from the supply, but when sufiicient amount of material has been drawn therefrom so that the carrier 5! has entered the shed and it then becomes relatively safe to release the loop of material L, Fig. 19, which is held at point 68, the parts [2! and a corresponding point on cam insert I23 permit raising of the point 68 so that the loop may be released and taken into the fab- 10 ric to tighten the selvage, it being understood that the release must occur so that the loop L will be taken into the fabric prior to a time when the inner clamp and cutter 32 are closed thereby to prevent further drawing of filling from the supply and thus to determine accurately the length of the pick so that only enough material may be inserted to be drawn across to the opposite side of the fabric and serve for the production of a suitable selvage. This clamp and cutter are closed at a time to determine the length of the pick and the cut end is then held as in Fig. 16 preparatory to repeating the cycle.

In this description, and in the claims, the term deflecting has been used as applied to bending or changing the path of the filling from one in which it would not be contacted by a carrier to one in which it may be taken by a carrier preparatory to its insertion thereby into a warp shed.

The term outside source of supply applies to a package of filling located relatively fixedly and beyond the range or the filling inserting means and obviously not earned thereby as in the case of the conventional any shuttle loom.

While one embodiment of the invention has been disclosed, it is to be understood that the inventive concept may be carried out in a number of ways. The invention is, therefore, not to be limited to the precise details described, but is intended to embrace all variations and modifications thereof falling within the spirit of the invention and the scope of the claims.
